The Aluminium Oxide Fibre Backed P40 180x22mm Conical Flap Disc is a premium high-performance abrasive tool designed for precision grinding and finishing. Engineered with a vulcanized multi-layered fiber backing, this disc offers superior heat resistance and stability, making it a professional alternative to standard sanding discs, especially when working on light gauge sheet metal where a refined surface finish is critical.

Ideally suited for mass industrial fabrication, automotive, nautical, and construction applications, this conical Type 29 disc excels in the rapid removal of spurs, sprues, and unwanted material. Its unique overlapped abrasive strip design ensures that as the disc wears, fresh aluminium oxide grains are continuously revealed, reducing clogging and maintaining a consistent, effective cut throughout the product's entire lifespan.

Frequently Asked Questions

Q: What is the difference between Type 27 and Type 29 flap discs?

Type 27 is a depressed center disc, while Type 29 (Conical) provides a more angled approach to the workpiece, making it ideal for blending welds and working in tighter corners.

Q: Can these discs be used on stainless steel (Inox)?

Yes, these discs are specifically designed for use on both ferrous metals and stainless steel (Inox), providing clean material removal without contaminating the surface.

Q: How does the fiber backing improve performance?

The vulcanized multi-layered fiber backing is highly heat resistant, preventing the disc from warping and ensuring a safer, more stable grind during high-speed operations.

Q: Which grit size should I choose for weld blending?

For rapid removal of heavy weld spurs, P36 or P40 is recommended. For a finer smoothing and blending finish, P60 or P80 is more appropriate.

Q: What safety precautions are necessary when using flap discs?

Always wear eye protection and safety gloves. Ensure the manufacturer-supplied wheel guard is in place and never use a disc that has been dropped or damaged.

Q: Do I need a backing pad for these conical flap discs?

No, these discs are designed to be mounted directly onto the grinder arbor, eliminating the need for separate backing pads and simplifying the process.
